One option would see the U.S. impose a 24 per cent tariff on steel imports from everywhere — including Canada. Another option would see a 53 per cent tariff on a smaller list of countries that does not include the northern neighbour.

The ultimate decision rests with the president, the commerce secretary cautioned: “(Trump) will decide what he’s going to do… He is not bound by these recommendations… He could do something totally different — or do nothing.”

The recommendations released Friday also include aluminum. The president is being asked to consider a 7.7 per cent tariff on all aluminum exports from all countries, or a 23.6 per cent tariff on just a few countries: China, Hong Kong, Russia, Venezuela and Vietnam.

The proposals also call for the use of quotas.

The options suggested include limiting all countries to steel exports equal to 63 per cent of their 2017 exports into the U.S., or a more severe quota for a smaller list of countries if Trump goes the more targeted route.

Ross said he anticipates countries might fight back: “It wouldn’t surprise us if there were (retaliation).”
